Common Questions About Cu-Pb-Zn Processing Technology. Among the separation of copper, lead and zinc ores, copper ore is relatively easy to be sorted. But in many cases, copper ore is symbiotic with lead-zinc ore, and these three kinds of ores can be studied together in the discussion of mineral processing technology.

Mar 05, 2017 Zinc. Copper is the least active of these three. I base this choice on the one type of reaction that metals typically undergo - oxidation. If you consult a list of what is known as reduction potential, and which is very useful in determining the manner in which chemicals oxidize or reduce, you find that zinc is considerably more prone to oxidation that is lead, which in turn is more prone to ...

Xinhai Cu-Pb-Zn Ore Dressing Process It is reported that more than 90% of non-ferrous metal ores (copper, lead, zinc, etc.) adopt flotation process, especially for
leached 46% Cu, 95% Co, 85% Zn, 92% Pb and 79% Fe with no selectivity at pH 0, than in basic medium (NH4OH). The modified slags by quenching in water had leached 89% Cu with a high selectivity as base metal extractions are less than 1% for Co, Zn, Pb and Fe at ambient temperature and pH 12.
Cu-Pb mixed concentrate regrinding process saves the grinding cost without fine grinding all the ores are, and it makes further monomer dissociation to create favorable conditions for the separation of copper and lead. Case Case 1. Tibet Lead zinc Beatification Plant is one of our successful cases.
